Electrocardiography

Electrocardiograms (ECG) are a primary cardiac diagnostic test that measures the electrical activity in heart to identify overall cardiac function, arrhythmias and areas of ischemia and infarct. Standard 12-lead ECG breaks the 3D structure of the heart into 12 zones, each showing the electrical activity in that specific area of the heart. This narrows down areas where there are issues with coronary artery disease or electrophysiology issues. Many ambulatory heart monitors and consumer-grade ECG monitors use fewer leads so are less specific as to cardiac conditions or location of abnormal heart rhythms, but can show an issue that requires further diagnostic testing or treatment.

Researchers use deep learning, ECGs to detect hyperkalemia

A deep learning model trained on more than 1.5 million electrocardiograms can reliably detect hyperkalemia—or abnormally high potassium levels in the blood—among patients with chronic kidney disease (CKD), Mayo Clinic researchers reported April 3 in JAMA Cardiology.

Chest strap ECG effectively detects AFib

Electrocardiograms (ECG) acquired using a chest strap could be a quality alternative to traditional ECGs when used to diagnose atrial fibrillation (AF), researchers reported in the American Journal of Cardiology.

FDA clears ECG feature for ‘prescription-only’ smartwatch

Another smartwatch has received FDA clearance for an electrocardiogram (ECG) feature. But this one—the Study Watch from Alphabet’s health division, Verily—is a “prescription-only device” rather than a product marketed to all consumers.

Creator of AI-based ECG analysis named European Innovator of the Year

Cardiologs co-founder and CEO Yann Fleureau was named the European Innovator of the Year by MIT Technology Review. The company offers a cloud-based artificial intelligence (AI) platform that enables the detection of 14 cardiac arrhythmias through ambulatory electrocardiogram (ECG) readings.

USPSTF: Insufficient evidence to support AFib screening with ECG

The U.S. Preventive Task Force (USPSTF) issued a Grade I recommendation, indicating there is insufficient evidence assessing the benefits and harms of screening for atrial fibrillation (AFib) with electrocardiography (ECG) in patients 65 and older with previously undiagnosed AFib.

ECG left ventricular hypertrophy: A good omen before TAVR?

Patients without electrocardiographic (ECG) evidence of left ventricular hypertrophy were significantly more likely to die in the two years after transcatheter aortic valve replacement (TAVR), researchers reported July 30 in Clinical Cardiology.

Wearable ECG device increases AFib diagnoses

Individuals at high risk for atrial fibrillation (AFib) who utilized a home-based wearable electrocardiogram (ECG) patch had a higher rate of AFib diagnosis after four months compared to delayed monitoring.

USPSTF: Do not screen asymptomatic adults for CVD using ECG

The U.S. Preventive Services Task Force (USPSTF) issued a Grade D recommendation against screening with resting or exercise electrocardiography (ECG) to prevent cardiovascular disease events in asymptomatic adults at low risk of CVD events.
